With reference to figure 2, shown a kind of method 200 that transmits and receives efficient for improvement of channel descriptor.When describing method 200, will can put into practice with any other suitable system or equipment although be to be understood that method 200 with reference to figure 1.Also can be with reference to figure 3 or 4, they have shown the example of a plurality of channel descriptor intervals and the example of frame respectively, although the present invention is not subject to these specific examples.And, the specific order that the step of method 200 is not limited to present in Fig. 2.The method of this invention also can have more or less step than the step that shows among Fig. 2.
In step 210, in wireless communication system, the normal channel descriptor can periodically be broadcasted at the interval of setting, and these normal channel descriptors can be received.In step 212, can change modulation system.Can provide the channel descriptor count of the indication that modulation changes periodically to be launched, and this change can be detected, shown in step 214.
For example, with reference to figure 1 and 3, the BS110 of system 100 can broadcast normal channel descriptor (CD) 310 on the gap periods ground of setting, and MSS112 can receive one or more conventional CD310.For instance, conventional CD310 can be downlink channel descriptor (DCD) or uplink channel descriptor (UCD), and the both describes in the 802.16e standard.As known in the field, CD310 can comprise the relevant information of modulation system that should use with the modulation system that is adopted by BS110 or MSS112.So, term channel descriptor can mean any data block that comprises the information relevant with modulation system.In addition, modulation system can be to information how decoded, modulated and/or emittor/receiver between provided any suitable agreement of guidance by exchange.
MSS112 can use the information among the CD310 to determine how to decoding from the transmission of BS110 and how the transmission to BS110 being encoded.As known in the art, CD310 can be launched at the interval of setting, and double-head arrow can represent the time quantum between the CD310 transmission, or CD at interval 312.As discussed previously, CD interval 312 can be longer relatively on the duration.
With reference to figure 4, shown the example of the part of frame 410.Frame 410 can be used for carrying the information between BS110 and the MSS112, and for example can be that OFDM inserts (OFDMA) frame.In this example, frame 410 can comprise channel descriptor count (CDC) 412, and as known in the art, this CDC can provide the indication of the modulation system of change.That is to say, BS110 can revise its modulation system and will be used by MSS112 those, and in response, BS110 can revise the counting of CDC412.MSS112 can detect the change of modulation system by CDC412.In a scheme and unqualified, CDC412 can be up link CDC or down link CDC, and it is comprised in the uplink map 414 or downlink map 416 of frame 410 respectively.Frame of broken lines has been represented uplink map 414 or downlink map 416, although they can be the discrete parts of data.
Come with reference to figure 2, in step 216, setting interim that can be between the normal channel descriptor is launched one or more supplementary channel descriptors, and can receive these supplementary channel descriptors again.In step 218, can periodically launch pointer, and this pointer can be used to identify the arrival of one or more supplementary channel descriptors.
With reference now to Fig. 4,, frame 410 can also comprise pointer 418, and this pointer can be the broadcasting steering needle as describing in the 802.16e standard for example.Pointer 418 can also be the part of uplink map 414 or downlink map 416.With reference now to Fig. 1,3 and 4,, as mentioned above, BS110 can change by its modulation system with the MSS112 employing.The information relevant with this change can be contained among the arrow CD310 pointed.As known in the art, MSS112 can enter sleep pattern continuously to preserve energy.Therefore, after the BS110 emission, MSS112 can wake up at the CD310 that comprises new modulation intelligence.Because the long interval 312 between the CD310, MSS112 had to wait for unacceptable time quantum before can receiving the next CD310 that comprises new modulation intelligence.
In order to overcome this problem, BS110 is in the interim of setting, and for example the CD interval 312, can launch one or more additional CD314 between conventional CD310.For example, the information still less that provides than conventional CD310 can be provided additional CD314.Especially, additional CD314 can only comprise the information about the difference between new modulation system or the new and old modulation system.Though this process can be saved bandwidth, should be understood that the present invention is not limited thereto, can be similar to conventional CD310 because replenish CD314.Because the present invention is applied to up link and down link, additional CD314 can be additional CD314 up link or down link.And conventional CD310 and additional CD314 can be the parts of frame 410, although channel descriptor can not be a part that arrives each frame 410 of MSS112.
In a scheme, CDC412 and pointer 418 can be launched continually, for example in each frame 410.For example, frame 410 can be long for 5 milliseconds (ms).Like this, when MSS112 woke up from sleep pattern, MSS112 can promptly receive CDC412 and pointer 418.Thereby if BS110 has changed modulation system, when MSS112 woke up, it can determine this change from the value of CDC412.In a scheme, MSS112 can access pointer 418 with determine CD at interval in 312 next channel descriptor when available.Probably, next available channel descriptor will be to replenish CD314, as relative with conventional CD310, may be the possibility of conventional CD310 although there is next available descriptor.MSS112 can take suitable action at this point, for example keeps clear-headed for the reception (or conventional CD310) that replenishes CD314 or even returns sleep pattern and wake up when additional CD314 (or conventional CD310) arrives.
Replenish CD314 (or conventional CD310) in case MSS112 receives, it can know that any modulation changes, and MSS112 can take suitable action.Like this, MSS112 can be rapid rectification change and take necessary step to limit the interruption of its operation.Additional CD314 can periodically be launched with any suitable speed, as long as they help to reduce following time quantum, namely will need be used for obtaining the time quantum of new modulation intelligence by MSS112 usually.In addition, additional CD314 can 312 be launched at interval at one or more CD, and in case finishes the emission that BS110 can recover channel descriptor at their regular interval.
Though have illustrated and described the preferred embodiments of the present invention, should be clear, the present invention so limits.To those skilled in the art, under the prerequisite that does not break away from the spirit and scope of the present invention that define as the claim of being added, can carry out a large amount of modifications, change, variation, alternative and of equal value.
